Title: Planographic printing plate and method for preparing same
IPC: B41N3/03
Filed: 1963-10-03
Abstract: A hydrophillic layer is formed on e.g. an aluminium plate for use in planographic printing by treating the plate with a solution of a fluoride selected from the tetrafluorides of transition metals, the complex transition metal hydrofluoric acids containing four, five or six fluorine atoms, and the alkali metal, alkaline earth metal or ammonium salts of such acids, and simultaneously or subsequently treating with chromic acid.  Examples are: ZrF4, H2ZrF6, K2ZrF6, Na2ZrF6, KZrF5, NaZrF5, TiF4, K2TiF6, HfF4, K2HfF6, NaHfF6, CaZrF6, and (NH4)2ZrF6.  The fluoride may be present in an aqueous solution in an amount from 0:01% to 1% by weight.  The bath temperature is 70 to 180 DEG F., and the pH 3.5 to 5.  A soluble zinc salt may be added to the bath.  The chromic acid bath contains 0.001% to 2.5% by weight of CrO3 and is at a temperature of 70 DEG  to 180 DEG F.  The plate is subsequently coated with a light sensitive material e.g. diazo resins, bichromated albumin, gum, casein, furfural-acetone condensation products or cinnamyl resinous materials.  The plate may be initially cleaned and treated with an activating acid e.g. phosphoric, chromic, nitric, sulphuric or oxalic.

Title: Improvements in or relating to photographic reproduction
IPC: G03G5/05
Filed: 1957-12-17
Abstract: An electrophotographic plate is made by forming a composition comprising a water-soluble resin-forming substance or substances in aqueous solution and a photoconductive substance, applying the composition to a support to form a layer removing the water from the layer and reacting the resin-forming substance or substances to convert them irreversibly to a water-insoluble resin.  The reaction may be effected by heating in the presence of a vapour catalyst, or a solid catalyst contained in the coating composition.  Suitable resin-forming substances are unpolymerized or partially polymerized urea-formaldehyde, melamine formaldehyde, aniline formaldehyde, thiourea-formaldehyde, cyanamide formaldehyde, diacyandiamide formaldehyde and mixtures thereof. The coating composition may include, in addition to the resin formers and photoconductor substance, fillers, waxes, plasticizers, water-proofing agents and antidiscolorant agents, and dye sensitizers such as Rose Bengal and Rhodamine B to alter the spectral sensitivity.  In one example finely divided zinc oxide is dispersed in a solution of melamine formaldehyde to which a quantity of the catalyst hexamine is then added.  After dilution with water the composition is coated on paper. The coating is then cured in an oven at 120 DEG C. and subjected to infra-red p  radiation and the paper subsequently rehumidified with steam.  In another example a urea-formaldehyde resin solution and ammonium chloride are dissolved in an aqueous solution of the di-sodium salt of 2, 5, bis-(p-sulphomethyl-amino-phenyl)-1, 3, 4-oxodiazole and the solution poured on aluminium sheet and cured as before.

Abstract: 345,622. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London. -(Stevens, C. E.; 18, Rue Boudewyns, Antwerp, Belgium.) Dec. 24, 1929, No. 39378. [Class 40 (iv).] In systems employing line-finders in tandem, faults which may cause the second line-finders to hunt indefinitely are traced by means of a faultlocating circuit which hunts for the particular first line-finder affected and by blowing its fuse enables the calling line to be extended over another switch. Faults may arise due to disconnections in the testing or holding leads or to faulty operation of subscribers' line and cut-off relays. In order to trace a fault the attendant operates a key BAK individual to a particular group of first line-finders and a circuit is completed over a contact of the second line-finder starting relay Cslr for the power magnet P of the fault-locating switch. When wiper a reaches a contact marked by battery over a front contact of relay Ltr and corresponding therefore to a first-finder circuit LF1 for which second finders LF2 are hunting, relay Dtr operates to stop the fault-locating switch and connects up relay Dsr which starts a timing switch TA. If the finder circuits are in order, the release of relay Ltr following the successful operation of a second finder causes the fault-locating switch to move on to the next link circuit over which a call is being set up. If, however, relay Ltr has not released by the time switch TA reaches its final position relay Dtr is operated and locked over release key RK closing a circuit for relay Scr which lights group lamps PL and connects direct ground to wiper a thus blowing the fuse in the first finder LF1. The calling line is seized by another first finder and a visible and audible alarm of the blown fuse is given. The position of wiper a indicates the particular circuit which is faulty.

Abstract: 928,703. Endless conveyers. SAPAL S.A. DES PLIEUSES AUTOMATIQUES. Nov. 3, 1961 [Nov. 14, 1960], No. 39417/61. Class 78 (1). In a method for the automatic control of a pusher arm 24 so that the number of articles 1 held by a stop 4 lies between predetermined limits each article 1 is detected by a photo-cell arrangement 5, 7 which feeds a positive impulse to a storage mechanism 12 to 15 by means of a ratchet 10 rotating a sun-wheel 12. The speed of electric motor 26 driving the pusher arm 24 is controlled by a resistance 29 varied in accordance with the position of planet wheels 13. Each rotation of disc 18 feeds one article 1 to a packing machine (not shown) and by means of worm 16 feeds a negative impulse to the storage mechanism 12 to 15 by a rim 15 acting on planet wheels 13. The rate of pushing is thus determined by the number of articles held by the stop and is so arranged that this number is held between set limits. The pusher may feed two objects at a time to a twin packaging machine. The epicyclic storage mechanism may be replaced by an electrical impulse storage device.

Abstract: 1,081,454. Electric calculating apparatus. KIENZLE APPARATE G.m.b.H. Sept. 16, 1965 [Sept. 17, 1964], No. 39562/65. Heading G4A. A switching device for use with an accounting machine having mechanical calculating and storing devices and for verifying that values such as statutory deductions from salaries &c., set in a keyboard each fall within one of a plurality of predetermined groups includes a contact assembly K which identifies the magnitude of the set value by the selection of magnitude identification relays G. The contact assembly is connected to relays G by a distributer circuit V and AND-circuits U1-U3 whereby, for an unambiguous digit set in the contact assembly, the relays G are directly energized by the circuit V1 whilst, for an ambiguous digit, the outputs of the distributer circuit are connected to the respective inputs of the AND-cirouits co-operating with the relays G, the outputs of said switches in turn being connected to the relays G. As shown, if a value, e.g. 660À00 is set, the conductors 4D, 6Z and 5D, 6Z are connected to each other thus pulsing conductors E2 and E5. Conductor E2 leads via V2 to input I of U2 and input II of U1. Conductor E5 leads via V5 to input I of U3 and input I of U1. The inputs of U1 allow a pulse to be applied to the output A4 of U1 energizing relay G1 which corresponds to one of the groups (wage scale II, (DM660À00- 749À99), Fig. 1, not shown). With relay G1 energized diode network B1 is switched in and three lines of the network call up storage devices of the appropriate values (K1, K5, K6, Fig. 1, not shown). The switching in of the relays for calling up the stores is only effected when the machine carriage has reached the correct column positions. Thus the control relay K1 is only operated if in the appropriate column positions (WS2, Fig. 1) the contacts wk2 have been switched via the carriage position relay (WK2, Fig. 4, not shown). In this carriage position (WS2) a stop is set in the third row of a control panel for the contacts (c, Fig 4), so that the corresponding relay (WK2) is energized (via a, b1 c1 and d2). In this position contacts wk2 are closed and the relay K1 is energized. The relay RB1 is at the same time switched in series as the constant value K1 was, to be computed as the amount for the deduction (health insurance) in carriage position WS2 and this amount is deducted from the gross earnings, the relay RB1 giving the respective instruction therefor.
